Laminated with nylon, its simple design safeguards any kind of scope from dings and scratches, dust, dirt, and moisture. Neoprene has a 5% moisture absorbency which takes moisture (condensation and sweating) away from the scope and helps protect it from rust and corrosion. The nylon shields against the elements. Simply stretch both ends over your scope. The recommended fit is either "relaxed same length" or slightly stretched. The Scopecoat XP-6 Flak Jacket fits scopes for law enforcement (SWAT), Bench Rest, Varmint, Leupold(TM) and Sniper scopes, as well as all tactical weapons including pistol, electronic, aim point, pro point, and the Bushnell HoloSight(R).
